FEEDING MECHANISM FOR CARDlNG-ENGINES.

SPECIFICATION forming part of Letters Patent No. 650,220, dated May 2.2, 190d Application filedMay 5, 1899. Serial No- 715,'749. (No model.)

To all whmn it may concern:

Be it known that I, EDDO V. BATES, a citizen of the United States, and a resident of Dracut, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Feeding Mechanism for Carding-Engines, of whichthe following is a specification.

My invention is an improvement of my patent of February 19, 1895, No. 534,418, and also of my patent of October 11, 1898, No. 612,303, relating to feeding mechanism for carding-engines; and it consists in the simplification thereof and addition of new and useful improvements thereon. Its objects are to lower the driving mechanism and the sprocket-chain, to permit greater range of adjustment of the parts for laying a shorter or longer sliver, to decrease the weight of all the parts, to permit greater facility of access to all parts, and'to providea compact and positive-action distributingcarriage. I attain these objects by means of the mechanism illustrated in the accompanying drawings, in which similar letters and numerals refer to similar parts, and in which Figure 1 is a front perspective View of the whole apparatus. Fig. 2 is a rear perspective view. Fig. 3 is an elevation of one of my end standards. Fig. 4 is a sectional view of the fluted and plain rolls in the distributing-carriage. Fig. 5 is a section through the line 2 z of Fig. 7. Fig. 6 is a transverse sectional view of a portion of the sleeve 1" and shaft, together with its support; and Fig. 7 is a top view of the adjustable driving mechanism for the sprocket-chain and distributing-carriage.

The base-plate 10 supports at its ends the standards y 11 Figs. 1, 2, and 3, which are firmly connected by rods Z and m and carry shaft 2' in suitable bearings q q.

The support a, attached by collars n and Set-screws to the rods Z and m, forms a collar or bearing and carries the shaft-connecting sprocket e and bevel-gear c and also forms a U-shaped projection, along which may be moved the collar 1* by means of shoulder s and set-screw t. (See Figs. 5 and 6.)

Power is transmitted to the apparatus by shaft a, carrying bevel-gear b, which meshes with bevel-gear 0, thus giving motion to the shaft, on which are affixed gear d and sprocket e, as well as bevel-gear 0. Gear 01 meshes with gear f, which through a connecting-shaft bearing in the collar 7' transmits power to the bevel-gear g at the other end of the shaft. This gear f is attached to the shaft by means of a set-screw or in any other suitable manner and may be replaced by a larger or smaller gear at pleasure, the collar r and gear 9 being adapted to slide on support a and to be held in place by means of spur s and set screw 15, and thus keep gears f and d enmeshed. Bevel-gear g meshes with bevel-gear h, which may be so adjusted on the 'splined shaft 11 by means of a set-screw or other suitable device as to always mesh with g when gear f is changed.

The endless chain 19 traversesand is propelled by sprocket c and also traverses sprocket e and moves the distributing-carriage backward and forward by means of a projecting pm which engages throughout its course the slotted tongue 8, firmly attached to the back of the carriage in the same manner as in my patents of February 19, 1895, No. 534,418, and of October 11, 1898, No. 612,303. The bearings of sprocket e are supported by collars 'n on rods Z and m, and by set-screws or other suitable appliances may be adjusted at any point along rods Z and m to correspond with the chain 19 when it is desired to increase ordiminish the length of the path of the distributing-carriage by adding links to or removing links from the chain 12. The supports 92 n are merely to give stifiness to the apparatus and serve as braces between rods Z and m.

The distributing-carriage is similar to the head described in my patent of February 19,

1895, No. 534,418, except that the slotted tongue 8 is attached lower down than in said patent to correspond with the lower position of chain p in this device. Motion is transmitted to the fluted rolls k k, which turn in- 5 lar devices to those shown in'my patent of I00 February 19, 1895, No. 534,418, taking motion from shaft 1 by sleeve bevel-gear 9, which slides upon the splined shaft 71, as there shown. The novel feature of this distributing-carriage consists in loosely mounting the plain rolls jj, which are smaller than the fluted rolls 70 it, upon the shafts'uw direotlylabove; rolls; 70 k and in aposition to roll upon the face of base-plate 10 while the carriage is in motion, thus acting as guides to it, while fluted rolls k k extend partially under the base-plate 10, and thus carry the sliver from the guide fi and deliveritimmediately under the said 7 plate 10 upon thefeed-table. M V

The advantages of my device are a lighter;- lower, and more compact frame and more coinpactvworkingv parts, dispensing with the intermediate driving-gear formerly used and bringingdown 'the'chain' to a level with "the driving shaft 7;, this permitting the operator to more conveniently keep the apparatus in order and to more easily reach over the whole deviceto the feed-table, facility inchanging thespeed of the feed-rollers by'changing the gearf forone larger or smaller and adj usting collar r and'gear: h to correspond, and facility in changingthe range of feed upon the feed- I table by lengthening or shortening chain p and adjusting sprocket e along rodsl and m. By'placing the two plain loose guide-rollsjj' upon the shafts v w and by having them smaller than the fluted feed-rolls kit the said rolls It It extend under the plate 10 and deriagetthan the rolls-used on the rocking arm inmy patent numbered 612,303, of October 11, 1898.. J7"

we In formgerdevices trouble'has arisen from pieces-of sliver or waste getting away'from' the'feed-roll's and winding upon'their shafts,

and this my plain rolls prevent, for if pieces should'wind upon them while traveli'ngone way as soon'as they reverse upon the return triplo'f the carriage these pieces are unwound and" thrown ofl. 'In case the sliver, or part of it; should work up above the fluted rolls. no harm is done, nor is it broken, for the plain rolls allow it to run by them and under the plate 10 without winding orbreaking it.
